This patch change arm prologue analyzer using code cache, in order to improve the performance of remote debugging. gdb.perf/skip-prologue.exp (measured by wall-time) is improved a lot, Original Patched Original Patched without dbg without dbg with dbg with dbg -marm 14.166741848 9.32852292061 11.4908499718 9.16302204132 -marm 14.6705040932 9.34849786758 18.2788009644 9.14823913574 \-fstack-protector-all -mthumb 34.4391930103 10.6062178612 13.7886838913 10.3094120026 -mthumb \-fstack-protector-all 34.9310460091 10.6413481236 25.3875930309 10.6294929981 gdb: 2016-12-09 Yao Qi <yao.qi@linaro.org> * arm-tdep.c (skip_prologue_function): Call read_code_unsigned_integer instead of read_memory_unsigned_integer.

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
